Answer:
See the explanation below.
Explanation:
This is because the vacuum chamber removes all the air contained and for this reason, there is no force that opposes the movement of the feather when falling. We must remember that the free fall equation of kinematics is not a function of the mass of an object.

where:
Vf = final velocity [m/s]
Vo = initial velocity [m/s]
g = gravity acceleration [m/s²]
t = time [s]
As we can see the mass of the object is not included in the equation.
Answer:
Hence, option (A) is correct answer.
Explanation:
None of the energy is created nor destroyed
Answer: The statement is false , if Jupiter and Venus somehow became the same size, Jupiter would still have more mass due to its density and composition and rocks, minerals, and etc.
